install docker on fedora 21
Step 1: Install Docker on Fedora 21
- As a matter of best practice, we’ll update our packages:
yum update -y
- Let’s install Docker by installing the docker-io package:
yum -y install docker-io
- Once the installation completes, we’ll need to start the Docker daemon:
systemctl start docker
- And finally, and optionally, let’s configure Docker to start when the server boots:
systemctl enable docker
- Step 2: Download a Docker Container
docker pull marina/fedora21-i386
Step 3: Run a Docker Container basic fedora container with a bash shell, we just run one command. docker run will run a command in a new container, -i attaches stdin and stdout, -t allocates a tty, and we’re using the standard fedora
docker run -i -t marina/fedora21-i386 /bin/bash
connect, or detach, from the shell without exiting use the escape sequence Ctrl-p + Ctrl-q.
sudo docker run -i -t -e DISPLAY=$DISPLAY -v /tmp/.X11-unix:/tmp/.X11-unix --rm marina/fedora21-i386 /bin/bash
Update image
